找不到jmap命令 [英] jmap command not found
问题描述
我正在尝试在我的 CentOS 服务器上使用 jmap 命令，但它一直告诉我该命令即使我安装了JDK，也找不到。
I'm trying to use the jmap command on my CentOS server but it keeps telling me that the command was not found even though I have the JDK installed.
这是命令的输出 java -version ：
java version "1.7.0_25"
OpenJDK Runtime Environment (rhel-2.3.10.4.el6_4-x86_64)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)
如何解决此问题？
推荐答案
您应该能够在 java-1.8.0-openjdk-devel-debug jmap Redhat / Centos上的>，或 java-1.7.0-openjdk-devel-debug 或 java-1.6.0-openjdk-devel-debug 包。要安装它，请以root身份运行以下命令：
You should be able to find jmap in the java-1.8.0-openjdk-devel-debug, or java-1.7.0-openjdk-devel-debug, or java-1.6.0-openjdk-devel-debug packages on Redhat/Centos. To install it, run the following as root:
yum install java-1.8.0-openjdk-devel-debug
为了完整性，这里是检查哪些包包含jmap的命令：
For completeness, here's the command to check which packages include jmap:
yum whatprovides '*/jmap'
这里是示例输出：
